Hosting a late night show is hard work, and last night (October 6) “The Tonight Show” stud Jimmy Fallon needed a little help from his predecessor Jay Leno.

Faking an injury, Fallon blurted out, "I don’t think I can continue, but of course, here at The Tonight Show, the monologue has to go on, so I think I’m gonna have to sub out. Can someone tag in for me please?"
